Geological characteristics of Te anomalies in South China

Abstract：To improve the analytical methods of Te by ICPMS, the authors made the detection limit of Te down to 0.005μg.g-1. For the South China regional geochemical mapping program, about 100 RGNR samples from each 1∶50 000 map sheet were combined into a single sample. The resulting 5 244 composite samples were subsequently determined by ICPMS. 3 giant and 2 regional Te geochemical anomalies were delineated in South China. Te anomalies in east Yunnan and west Guangxi are related to the distribution of limestone. Te anomalies in Chenzhou of Hunan Province, Shaoguan of Guangdong Province, Xianggelila of Yunnan Province, Daye of Hubei Province and Tongling of Anhui Province are related to copper polymetallic deposits.
